What 28305 covers
The surgeon makes a controlled cut through a midtarsal bone, adjusts its position or shape, and uses autogenous bone graft as part of the reconstruction. A familiar example is a grafted medial cuneiform osteotomy during reconstruction of flexible flatfoot. Orthopedic foot-and-ankle surgeons and podiatric surgeons perform these procedures in an operating room, commonly in a hospital or ambulatory surgery center.
Report this code when the operative work is a midtarsal osteotomy with autograft; code 28304 describes the related midtarsal osteotomy without autograft. The operative report should identify the bone treated, the osteotomy and correction performed, and use of autograft. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
